Refinamento AOD vs Refinamento VOD

O método de refino AOD é a abreviação de Argon Oxygen Decarburization (Descarbonização de Oxigênio de Argônio), no refino de aço inoxidável, reduzindo a pressão parcial de CO, para atingir o efeito de falso vácuo, de modo a reduzir o teor de carbono a um nível muito baixo e inibir…

Partes básicas da fabricação mecânica

Prendedores, rolamentos, engrenagens, molas, moldes e matrizes são as partes básicas da fabricação mecânica, que afetam diretamente a qualidade e a confiabilidade das máquinas. Prendedores, rolamentos, engrenagens, molas, moldes e outro ambiente de serviço são diferentes, a qualidade dos requisitos do material também é diferente. Fixadores de aço Os fixadores…

Q3:The Main Ways to Reducing the Burn Loss

Answer: Fine material principle to reduce the amount of slag. Reasonable slagging system. Reasonable oxygen supply system, loading system to reduce mechanical spattering. Thermal compensation technology, consume more scrap to reduce chemical burn loss. Reasonable re-blowing technology.

Short Stress Rolling Mills

New or expanded bars or wire rod production line is mostly used in H/V arrangement of short-stress rolling mill, it is compared with the traditional mill, this compact rolling line reduces the weight of equipment and plant construction costs. The characteristics of the short stress rolling mill: The rigidity of the mill is good, and the dimensional…

Roll Shape Inspection Ways

The rolls of hot rolling mill or cold cooling mill act key role in the rolling process. The shape (convexity, concavity, taper,etc) of the roll can impact the quality of final products. In the rolling process along the length of the roll, the distance between the upper and lower rolls should…
